transduction

 [trans-duk´shun]
the transfer of a genetic fragment from one microorganism to another by bacteriophage.

trans·duc·tion

(tranz-dŭk'shŭn),
1. Transfer of genetic material (and its phenotypic expression) from one cell to another by viral infection.
2. A form of genetic recombination in bacteria.
3. Conversion of energy from one form to another.
[trans- + L. duco, pp. ductus, to lead across]

transduction

(trăns-dŭk′shən, trănz-)
n.
2. The transfer of genetic material from one cell to another, especially a bacterial cell, through the use of a bacteriophage.

trans·duc′tion·al adj.

trans·duc·tion

(trans-dŭk'shŭn)
1. Transfer of genetic material (and its phenotypic expression) from one cell to another by viral infection.
2. A form of genetic recombination in bacteria.
3. Conversion of energy from one form to another.
[trans- + L. duco, pp. ductus, to lead across]

transduction

1. The conversion of energy in one form into energy in another.
2. The transfer of a gene from one bacterial host to another by means of a phage.
3. The transfer of a gene from one cell host to another by a retrovirus.

transduction

  1. the transfer of DNA from one bacterium to another, using a VIRUS as a vector. The donor is subjected to LYSIS, the recipient is infected with a transducing phage. See GENERALIZED TRANSDUCTION, SPECIALIZED TRANSDUCTION.
  2. the process of relaying a signal (e.g. a hormone) to an effector system to stimulate the appropriate cellular response.
  3. a process involved in conversion of one form of energy (e.g. light) into another (e.g. chemical).

transduction 

Generally, the conversion of one form of energy into another. Example: the transformation of light energy into receptor potentials in the photoreceptors of the retina (also called phototransduction). The absorption of light by the pigments of the photoreceptors triggers a cascade of biochemical events that leads to a change in ionic fluxes across the plasma membrane and to a change in resting potential from around −40 mV in the dark, to around −70 mV in light, that is a hyperpolarization of the cells. See depolarization; hyperpolarization; receptor potential; visual pigment.
